In order to select the better wine grape varieties, and improve wine quality evaluation standards, the paper made a cluster analysis of wine grape samples based on the selected 57 physicochemical indexes. It's also classified different categories of wine grape after comparing the results of the wine quality evaluation. SPSS for canonical correlation analysis was used to find typical indicators, which...
Based on wind speed sequences, three-layer neural network model of wind speed prediction is analyzed to obtain the selecting method of neural network input, output and hidden layers' node parameters, and to predict wind speed through rolling wind speed data. In accord with the nonlinear of wind speed sequences, a BP neural network model is established to forecast wind speed. The feasibility and validity...
Objective To Predict the basic luteinizing hormone (LH) and follicle stimulating hormone (FSH) levels in girls with precocious puberty using ultrasonic union artificial neural network. Methods In 71 girls with precocious puberty, the uterine and ovarian were examined with ultrasound. The back-propagation (BP) neural network was established using uterine volume, ovarian volume and the largest diameter...
